Description
Technical field
This utility model is related to myopia prevention technical field, and in particular to a kind of myopia prevention display accessory.
Background technology
With the popularization of electronic product, the age bracket for contacting electronic product is more and more lower, and excessively infatuated meeting is to vision or body
Body health works the mischief, and because existing display is primarily directed to adult's design, does not account for the specific demand of child.By
It is poor in child's ability of self control, it is in kind with more strong interest for fresh, extra supervising device is needed to this craziness
Behavior is limited.
The content of the invention
The purpose of this utility model is to provide a kind of myopia prevention display accessory, to solve above-mentioned background technology in propose
Problem.
For achieving the above object, this utility model provides following technical scheme：
A kind of myopia prevention display accessory, including shell, enclosure arranges minitype electromagnet and power supply, arranges on shell
Button and range sensor.
Further, the minitype electromagnet, range sensor and button are connected with power supply.
Further, the minitype electromagnet is plug-type minitype electromagnet.
Compared with prior art, the beneficial effects of the utility model are：
A kind of myopia prevention display accessory, reasonable in design, principle is simple, and using range sensor human body and display are detected
Distance, so as to control the switch of display by minitype electromagnet, during display is seen human body and display away from
From when reaching with a distance from setting, display can be automatically turned off.It is easy for installation, only this utility model need to be stuck on display casing
.
